Beautyrest Black Hybrid X-Class Medium Mattress Review

Updated January 24, 2022

Beautyrest Black Hybrid X-Class Medium Mattress

The Beautyrest Black X-Class Medium is a medium-feeling mattress made by Simmons and it comes highly recommended for its back support and pressure relief.  This model is the middle comfort of the four X Class hybrid models in the Beautyrest Black collection.  We've reviewed this bed's features and benefits, please read on for our expert review:

Comfort Scale Rating

The X Class Medium mattress is rated a 4 on our 10 point Comfort Scale (a 1 is hard, 10 is softest).  Most people will find a mattress with this level of comfort very appealing.  However, if you feel that your comfort preference is a bed that is either much firmer or very soft then you may want to consider one of the other three X Class models with a different comfort level.

Pressure Test Results

The Hybrid X-Class Medium mattress was tested with petite, average, and large body size people on their side and back sleeping positions to see what kind of support and comfort you can expect. (Learn how we test.) 

Our pressure test results show that this mattress is recommended for back sleepers of all body sizes and petite side sleepers.  The only 'not recommended' score that this bed earned was for the larger-sized body side sleeper which is due to the increase of excess pressure on the peak pressure points, the shoulder, and the hip.  If you consider the images below, the bright red areas that are highlighted in the larger side sleeper exhibit where there's too much pressure on that particular joint.  The yellow areas in these images indicate where there's a rise in pressure above what is considered normal, or acceptable.  What you really want to see are vast areas of green and light blue which means that the body is getting the exact amount of back support and pressure relief necessary for a good night's sleep

Your body needs proper back support for correct spinal alignment.  Without correct alignment, you'll likely experience head and neck pain, lower back discomfort, stiffness, and extreme weariness the next day all due to low-quality sleep from improper spinal alignment.  Pressure relief in your mattress is just as important because excess pressure on your hips and shoulders can cause numb limbs which makes you roll around in bed to find a more comfortable position.  This then disrupts your sleep and makes for a pretty miserable sleep experience.  The X-Class Medium tested fairly well for proper back support and good pressure relief, particularly for back sleepers.

The Main Beautyrest Black Hybrid X-Class Medium Features in Detail

Hybrid X-Class Medium Cutaway Image

  1. 1. BlackICE Hybrid Technology

    This cool-to-the-touch cover works with several other layers of material to provide you with a cooler sleeping environment.  The BlackICE Hybrid Technology is exclusive to the Beautyrest Black collection of mattresses.

  2. 2. RightTemp Memory Foam

    Infuses highly conductive and strong carbon fiber for temperature management and durability in a pressure-relieving foam.  This is another layer of material that draws heat away from your body and expels it outwards for a cooler sleep experience.

  3. 3. Beautyrest Gel Memory Foam

    Gel Memory foam gives you exceptional pressure relief by contouring to the curves of your body for correct support.  The infusion of gel into the memory foam is an added cooling feature for more temperature regulation.

  4. 4. Firm Comfort Foam

    This layer of comfort foam gives you the stable support that you need for pressure relief on your joints and proper spinal alignment.  

  5. 5. T3 Pocketed Coil Technology

    Exclusive to Beautyrest Black, this coil is made with three steel strands that are interwoven for extra durability and excellent support.  They work to provide individualized back support and pressure point relief throughout the night.

  6. 6. Energy Foam

    1.5 inches of the very durable Energy Foam creates a supportive, durable foundation for the no-flip mattress design.

Conclusion

The Black Hybrid X Class Medium mattress is a medium-feeling bed by Simmons.  This comfort is popular because it makes a great compromise for couples who have different sleep preferences.  There are other comforts in the X-Class models if you feel that something softer or firmer might be your preference though.  This model functioned pretty well during our pressure testing phase, earning 4 out of 6 'recommended' scores for the various body size/sleep position combinations.  It demonstrated excellent supportive capabilities and really good pressure relief throughout testing.  It did earn one 'not recommended' score, however, the larger-sized person who's a side sleeper might feel this bed causes a bit too much pressure on the hips and shoulders.

One of these mattresses' main features is 2 inches of Beautyrest Gel Memory Foam.  Gel beads are infused into the memory foam which helps air movement while being very soft and durable.  BlackICE Hybrid Technology is another feature that gives you a cooling sensation that also works to keep you cooler at night.  The multiple layers of foam combined with the T3 Pocketed Coil Technology creates plush comfort and conforming support.  Our pressure testing has confirmed that this mattress performs particularly well for back sleepers with its excellent back support for proper spine alignment.  

The cost for one of these beds, in Queen size, is $2,599, which is the lowest price of the four X Class models.  Despite it being up to $800 less than the other three models the X Class Medium does not lose out on premium materials or construction.  This model is a great choice for a Beautyrest Black model, so long as you're willing to pay for premium quality.  I recommend this bed to anyone looking for a premium quality mattress, particularly if you're a back sleeper.
